<P>PROBLEM TO BE SOLVED: To provide a medical stopcock with a cap with which it is possible to link in communication or block any branch pipe from among a plurality of branch pipes, and also with which it is possible to easily expel air inside a branch pipe which is not being used. <P>SOLUTION: The medical stopcock A comprises: a chamber part 11; a main upstream branch pipe 12, a downstream branch pipe 13 and a supplementary upstream branch pipe 14 which are connected to the chamber part 11, respectively; a rotary valve 15 which can link in communication and block the areas between the main upstream branch pipe 12, downstream branch pipe 13 and supplementary upstream branch pipe 14 and the chamber part 11, respectively; and a cap 18 which can be attached to and detached from the supplementary upstream branch pipe 14. Also, the cap 18 is provided with an insertion part 18a to which a filter 19 is fitted, and the movement of liquid between the chamber part 11 and the supplementary upstream branch pipe 14 can be prevented when the cap 18 is fitted to the supplementary upstream branch pipe 14 with the insertion part 18a inserted into the supplementary upstream branch pipe 14. <P>COPYRIGHT: (C)2010,JPO&INPIT |
